MACHINE FOR FORMING- OPENINGS IN WOVEN FABRICS.

Specification of Letters ratent'.

Application filed July 26,1912. Serial m. 11,017.

To all whom it may concern:

Be it known that I, BERT R. BENJAMIN, a citizen of the United States,residing at Oak Park, in the county of Cook'and State of Illinois, haveinvented certain new and useful Improvements in Machines for FormingOpenings in Woven Fabrics, of which thefollowing is a specification.

My invention relates to machines for forming openings in woven fabrics,and in particular to a novel mechanism for puncturing same in a mannerwhereby the threads thereof remain unbroken and the openings thereinretain their original form permanently; the object of my invention bemgto provide a woven fabric in the form of belting or straps with openingsadapted to receive the tongue members of buckles in the same way as theholes in ordinary leather straps. I

These objects are attained by means of mechanism, one embodiment ofwhich is illustrated in the accompanying drawings, in which Figure 1 isa side elevation, partly in section, of a machine desi ed to puncturefabric in a manner following the method to be described; Fig. 2 is adetached detail of Fig. 1, on an enlarged scale and designed toillustrate the operation of the puncturingmechanism; Fig. 3 is a viewsimilar to Fig. 2, and representing the fabric as pierced by thepuncturing mechanism; and Fig. 4 is a view showing a sample of thewoven, fabric provided with openingsmadeaccording to my method. l l

The same reference numerals designate like parts throughout the severalviews.

1 represents the frame of the machine, having a primary powertransmitting shaft 2 journaled upon the upper end thereof, and a secondshaft 3 near the lower end, motion being transmitted to shaft 2 by meansof a pulley 4 and from shaft 2 to shaft 3 by means pulley 5 and belt 6.

7 represents a sliding head carried by an arm 8, formin part of theframe 1, and having a spin e 9 journaled therein.

10 represents a pinion connected with the upper end of the spindle in amanner to transmit motion thereto and permit the spindle to slideaxially therethrough, the

pinion deriving motion through bevel gear wheel 11 secured to the shaft2. The movement of the sliding head 7 is controlled in Fig. 4.

a common way by means including a toothed rack 12 carried thereby, apinion 13 ournaled upon arm 8 and connected with a hand lever 14 15represents a bed member integral with frame 1 and having journaledthereon. a shaft 16 in axial alinement with the spindle 9, having a capmember 17 at the upper end thereof, and 18 represents a bevel gear wheelsecured to the lower end of the shaft and engaging with a pinion 19secured to shaft 3, whereby the shaft is rotated in a direction oppositeto that of the spindle.

20 represents a tapering pointed puncturing member having a shank 21that is re-. ceived by'a socket formed in the lower end of spindle 9,and a collar portion 22 at the base of the shank, and 23 represents atapering tubular member received by an axial bore in shaft 16 andadapted to receive the tapering puncturing member 20.

It is desirable that a viscous fluid be applied to the fabric at thepoint of engagemerit-with the puncturin instrument, and for a supply ofsuch fiui there is provided a receptacle 24 carried by the frame of themachine and having a feed pipe 25 leadin therefrom to the desiredposition, the feed of fluid being controlled by means of a valve 26.

In operation the fabric is placed upon the tubular'member 23, that isprovided with a raised portion 23 at the upper end thereof thatcorresponds with the lower surface of the collar 22, and the rotatingpuncturing member 20 is brought in contact therewith and passed throughthe material, crowding the warp and weft threads laterally, and

simultaneously with the operation a viscous fluid, as glue or sizing,flows toward the opening being formed, and when the coll'ar 22 reachesthe surface of the fabric the premure is continued and the fabric isheld for a. period between the oppositely revolving members20 and 23,resulting in a permanent opening being formed having a surroundingsmooth surface, as shown in While I have in this applicationspecifically described one embodlment which my invention may assume inpractice, it is, of course, to be understood that the form thereof shownfor purposes of illustrationv may be modified without departingv from'the spirit of my invention, and that l intend to 110 Patented (lot. 26,i915.
